Bigger is not always better. One of these days that will sink in to my thick head. When my sons were younger we did cub scouts. It seamed like a full time job trying to come up with projects for them to do. In one cub scout book I found instructions to make a kite. I thought, cool, I'll double all the dimensions, and make them real big. Not a good idea, the string cut up their hands pretty good, and they thought they could still fly them if they wore their bicycle helmets, when they came down, they came down hard.
Here is a picture of the play set I built. My wife calls it the slide of death.
